Noctua is well recognized for evolving and creating some of the world’s silent and finest performing cooling gears. Since their formation in 2005 they have rolled out some of the best high-end CPU Coolers and Thermal Compounds.

Currently we got our hands on the newly released Noctua NH-U12A CPU Cooler. The NH-U12A was launched and presented as 5th generation of its award winning U12 Series of solid size finest CPU Coolers. The NH-U12A comes with reshaped heatsink and countless new characteristics and it’s intended to dissipate as much heat as possible from your CPU with its 7 heat pipes to ensure cooler processes. The included 2x NF-A12x25 PWM 120mm cooling fans provide noiseless and trouble-free user experience, their tan and brown color scheme may not be to everybody’s taste but sure keep the temperatures down to an absolute minimum. Noctua also claims that NH-U12A can go head to head with larger 140 mm coolers.

The bundle contains SecuFirm2 mounting kit that arrives with NT-H1 thermal paste, the mounting kit is user friendly and quite easy to work with. The cooler is well-matched with both Intel and AMD current and legacy sockets. The cooler supports high profile memory and offers 32mm of RAM clearance on the default fan position but make sure to install the cooler in the right method else it will cause memory clearance problems.

Inside The Package

The NH-U12A arrives in a tan themed box, the top of the box highlights about core characteristics of the cooler such as 100% RAM compatibility on the most recent Intel and AMD sockets, 2x NF-A12x25 PWM fans, included NT-H1 thermal compound and 6 years of warranty. Further sides of the box show detailed information’s of the NH-U12A being the 5th generation of the NH-U12 design and provided stuff inside the box.

After opening the box, we are greeted with the Noctua’s SecuFirm2 mounting system which contains all essential parts in a isolated box.

Noctua’s SecuFirm2 arrives with mounting bracket for all current and old CPU sockets.

Installing the cooler on the motherboard was not hard. Firstly you will have to remove the pre-installed legacy brackets on an AMD motherboard and then place four AM4 (Gray) spacers on top and with the spacers in positioned you able to secure the mounting bars with the included screws.

Now apply the included NT-H1 thermal compound and mount the cooler with the Noctua’s logo facing to the backside of the case and confirm it. Lastly mount the tower, attach the fans to the both sides of the heatsink of cooler and power them into the CPU fan header on the motherboard.

Test Bench and Methodology

All the testing was done in Corsair Obsidian 500D case with 4x Aigo DR12 Pro 120mm fans in which three fans were set at the front to in-take and one fan at the rear out-taking the air. The ambient room temperature was 33-degree Celsius. All the fans were controlled by the integrated fan controller and were set at 100% fan speed. The thermal compound being used is the Noctua NT-H1 and the same thermal compound is being used for all coolers to confirm standardization.

All the tests were conducted on stock and overclocked configurations on our AMD system. At stock the processor was set a 3.00GHz with voltage set to auto and at overclocked configuration the processor was set at 3.80GHz at 1.33V. For minimum temperature testing we set the system to idle for 30 minutes to confirm the temperature have stabilized and for the maximum temperature testing we ran AIDA 64 stress test for 30 minutes to get the highest possible temperature, all results are showed as delta temperatures and these are calculated by subtracting the ambient room temperature. The same methodology was used for all the coolers.

  • AMD Ryzen 7 1700
  • Asus Prime X370 PRO
  • Corsair Vengeance RGB Pro (2x8GB) 16GB 3000MHz
  • MSI Duke GTX 1070Ti
  • Western Digital Black 500GB M.2 NVMe SSD
  • XPG SX950U 480GB SSD
  • Seagate Baracuda 2TB 7200RPM HDD
  • Antec EAG 650W 80+ GOLD

Software used:

  • Aida64 Extreme
  • CPUID HWMonitor


We were expecting NH-U12A to go head to head with the Reeven Ouranos and it did as promised. Noctua NH-U12A evenly matched with the 140mm cooler in the idle temperature.

Surprisingly, NH-U12A out performed the Reveen Ouranos in Aida64 FPU stress test at both Stock and Overclocked configurations.

At full fan RPM, the NF-A12x25 PWM were extremely quite when compared to the Reeven Ouranos 140MM fan. The fans were nearly silent even at 100% speed and were barely noticeable.

Final Thoughts

Noctua NH-U12A without any doubt is one of the best air cooler available in market that ensure smooth and quite user experience. With it’s premium build quality and signature high performance fans, Noctua NH-U12A is all you could ask for. The cooler is compatible with high profile RAMs, Easy to install and comes with 6 years of warranty.

We at PPG absolutely recommend Noctua NH-U12A and Special Thanks To Noctua for giving us the opportunity to review their Cooler.
